in this paper, a new structure possessing the advantages of low-power consumption, less hardware and high-speed is proposed for fuzzy controller. the maximum output delay for general fuzzy logic controllers (flc) is about 86 ns corresponding to 11.63 mflips (fuzzy logic inference per second) while this amount of the delay in the designed fuzzy controller becomes 52ns that corresponds to 19.23 m...

Proportional-Integral (PI) controllers are conventionally used in speed control applications of dc drives. These controllers provide good steady state response but do not provide better dynamic response during transient conditions. In this paper an effort is made to design a fuzzy logic controller (FLC), which can provide a better dynamic as well steady state response for speed control applicat...

A new fuzzy bang–bang relay controller (FBBRC) is introduced in this paper. The new controller is inherently optimal due to its bang–bang property. The controller has fuzzy decision-making capability in its inputs and have two fixed levels bang–bang output. Consequently, the tuning of FBBRC is restricted to input parameters only in comparison to standard fuzzy logic controller (FLC) where the o...

Abstract: A combination of Direct Torque Control (DTC) and Space Vector Modulation (SVM) for an Induction Motor (IM) drive is defined in this paper. A two-level SVPWM inverter is delivered to the induction motor drive. Using IM model in the stator D-Q axes reference frame. The inverter voltage is achieved based on inputoutput feedback linearization control. This paper signifies a Fuzzy Logic Co...

The aim of this research is to design and simulate a fuzzy logic controller (FLC) to control the cell multiplexing in Asynchronous Transfer Mode(ATM) networking , which is a high performance cell oriented switching technology that utilizing of small size packet to carry different types of service for traffic and to show the effect of using the fuzzified variables (queuing message length and the...

moving obstacles (opponent robots) and a moving target (ball). Until now, many navigation methods have been demonstrated for robot soccer. Sim et. al. [2] proposed a four-mode control structure which has different controllers for four divided areas around a ball. Kim et. al. [3,4] proposed the uni-vector field method. Selecting two points, one in front and the other at the back of the ball, the...

A fuzzy logic- (FL-) based control technique for unified power flow controller (UPFC) to resolve the quality issues in transmission network is presented this paper. MATLAB/Simulink used design FL-based controllers shunt and series converters of UPFC, which validated on 4-bus system. In addition, performance suggested UPFC compared with PI (proportional integral), HC (hysteresis controller), MPC...

This paper introduces a fuzzy logic-based circadian lighting control system using flexibility of Light-Emitting Diode (LED) technology to synchronise artificial with (natural) Correlated Colour Temperature (CCT) characteristics. Besides for vision acuity, the Non-Imaging Forming effects affect human rhythms. Past works in spectrally tuning CCT or Spectral Power Distribution have used convention...
